WATC H-CAS E.

SPECIFICATION forming part of Letters Patent No. 298,509, dated May 3. 1884- (No model.)

To all whom it may concern Be it known that I, HORACE G. SKIDMORE, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Watch-Cases, of which the following is a specification.

My invention relates to a new and useful construction, in one integral piece, of the movement-ring part and of the baclerim part of a watch-case, and of the combination therewith of other useful novelties hereinafter explained.

The object of my invention is the production, at a moderate cost, of a practically dust and moisture proof watch-case of great con1- pactness, simplicity, and elegance.

My improved case being adapted to a great variety of watch-movements, none are here represented.

In the accompanying drawings, Figures 1 and 2 represent a form of my improvement applicable for use with a stem-winder watch of the hunter pattern,-Fig. 1 showing the members detached from one another, and Fig. 2 being an axial section of the casein its closed condition.

A characteristic and important feature of lnyimprovement is a peculiarly-formed annular piece of metal, A B, of which the portion A serves as the ring part to hold the watch-movement, (not here shown,) and of which the portion B does duty as the rim part or frame of the back, to which latter a panel, C, is removably attached by any suitable means, preferably those here shownthat is to say, the central opening of such rim part has a screw-thread, b, and a shoulder, 11, to

enable dust and moisture proof attachment of .ly screw-threaded riser, a, on front edge of said ring part A enables dust and moisture proof attachment of a correspondinglythreaded bezel, E. A riser or rabbet, d, on the outer front margin of center D enables the snapping thereto of a front cap, F, having customary hinge attachment, G, to said center. Screwing of the members 0 and D to and from the annulus A B may be facilitated by knurlings J. 1

In that form of my improvement which is designed for use with hunter eases, customary .or any suitable case-springs, K L, are attached in the accustomed manner to the interior wall of the center D, which center is for that purpose chambered, as represented.

hen designed for a stem-winderwatch, the ring part A of the annulus A B has an orifice, a, in alignment with the axis of the pendant H.

If preferred, the unexposed portion A of the annulus may be of cheaper metal than the other portions of that member, and be united to them by soldering.

A glazed bezel may be substituted for the all-metal cap 0 in open-faced watches.

Complete accessibility for regulating and other purposes is afforded by simple removal of the panel 0 without necessitating Withdrawal of the movement from the case.

I claim as new and of my invention 1. In a \VEttCh-OflSG, the annulus A B, in which the ring part A and the back-rim part B constitute one'integral piece of metal, substantially as and for the purpose set forth.

2. In a watch-case, the combination, with the casecenter D and annulus A B, of the separable dust-proof panel C, substantially as set forth.

3. In a watch case, the annulus A B, and case-center D, in combination with panel Cand bezel E, attached, in the was er described, at the back and at the front, respectively, of said annulus, for the purpose set forth.

4. I11 a watch-case, thechambered annulus A B, closed at rear and open at front, in combination with the case-springs K L, case-center D, and the pendant H, substantially as set forth.

In testimony of which invention I hereunto set my hand.

HORACE G. SKIDMORE.
